Iskra™ Rambling rose MEIhaiti – pharmaROSA® NEONATAL own‑root propagation material
Iskra™ Rambling rose MEIhaiti offers a distinctive vertical presence for pergolas, walls and arbours, combining an exhibition-grade display with reliable medium-vigorous growth suited to trained climber production in 5–7 litre containers. As an own-root pharmaROSA® NEONATAL cutting, it provides a renewable structural framework that supports long-term capacity planning and homogeneous batches for nursery and wholesale networks focused on thematic and collection rose gardens. Its bright scarlet-red colour holds well from bud to fade, retaining ornamental value through the main once-blooming cycle and then contributing orange-red hips for extended-season interest. The medium maintenance requirement aligns with professional regimes where occasional pest and disease control is standard practice, and its H6 hardiness helps it cope with exposed UK sites, offering dependable performance even in colder, wind-affected locations as part of robust national supply programmes. With a creeping, trainable habit that can be staked into 3–5 main canes, it lends itself to space-defining projects where exclusive, vertical garden features are required, developing roots in year one, stronger shoots in year two and full ornamental expression by year three for finished-product ranges aimed at retail and reseller channels.

Technical cultivar profile
| Parameter |
Data |
| Name and registration |
Registered as MEIhaiti, marketed as Iskra™ Rambling rose MEIhaiti, also known in exhibition contexts as Sparkling Scarlet; classified as a climbing rose within the Rambling rose collection. |
| Origin and breeding |
Bred by Marie-Louise Meilland in Germany around 1969, introduced by Meilland International (France) circa 1971; parentage is unknown, representing a Meilland hybrid Wichurana climbing selection. |
| Awards and recognition |
No documented competition, collector or lifetime awards are recorded for this cultivar; selection is based on long-term practical horticultural performance rather than show honours. |
| Growth and structural characteristics |
Creeping, trainable climbing growth reaching approximately 240–360 cm in height and 150–260 cm spread, with moderately dense, slightly glossy mid bronze-green foliage and a moderate level of prickles. |
| Flower morphology |
Semi-double, cupped flowers with a pronounced medium high-centred form, 13–25 petals and medium size (about 1.5–2.75 inches), produced in clusters; non-remontant, flowering once per season. |
| Colour data and phenology |
Scarlet flowers with slight orange tones; ARS code OR, RHS 46B outer and 46A inner; buds deep velvety scarlet, opening fiery red, then softening to coral-red shades while maintaining generally good colour retention. |
| Fragrance and aroma |
Very weak, subtly rosy fragrance of low intensity; flower form and petal count provide some pollinator access, though semi-double structure limits nectar and pollen availability compared with simpler flowers. |
| Hip characteristics |
Produces moderately abundant, spherical orange-red hips, around 16–24 mm in diameter, which follow the main flowering period and extend the ornamental contribution on pergolas, walls and arbours. |
| Resistance and winter hardiness |
Medium general disease resistance, with good black spot resistance and medium tolerance to powdery mildew and rust; hardy to around -15 to -12 °C, rated RHS H6, Swedish zone 2 and USDA zone 7b. |
| Horticultural recommendations |
Best used on pergolas, fences, walls and arbours; medium maintenance with occasional pest and disease control, ideally supplied as staked, trained 3–5-cane climbers in 5–7 litre pots for vertical ornamental roles. |
Iskra™ Rambling rose MEIhaiti brings reliable vertical structure, strong scarlet display and durable own-root frameworks for predictable, long-lived stands; consider it where you need stable, trained climber capacity and are planning your next production cycle.
